Swapping over to Moutul RBF600....question

[Phdpsy]

As I understand it, the 1LE fluid for the brakes and clutch utilize a single resivoir source. So to switch to a high performance fluid, what all,is involved? I'm used to vehicles with separate systems, so swapping brake fluid was easy. Car will be arriving Monday and this is among my first changes to make. Thanks.

Got mine from JDP also.
As I understand it, the brake system is your typical bleed the brakes and change the fluid. Once the separate clutch reservoir is installed, the only way to bleed the clutch system is through a bleeder that is only accessible behind the bell housing so what most do is use a turkey baster to suck out as much as they can and replace the fluid with the good stuff.
Maybe if needed someone else can chime in with the actual approach to take as my car has not arrived yet so Im not an authority

If you do not separate the clutch, you can bleed the brakes till the new fluid flows, start with the furthest bake first. You can press the clutch peddle about 30 times and that will cycle some of the oem fluid. That should get about 90%

EDIT: What part of Louisiana are you in?

Thanks for the initial thoughts. Why they made it a complicated process and overlapping system resivoirs is still strange to me. I'll also look into the JDP product.

If you want to piece the kit out yourself, here's what you need. The EPDM BMW hose is long enough for two kits. So if you have a buddy order the stuff together. This is what I used

NAPA 660-1698 EPDM bypass caps
BMW cloth covered brake hose 21521163714 $7.77 + $11.50 SH from bmwpartsweb.com
GM Hydraulic Clutch Reservoir 92065790
hose clamps

will it hurt the system to replace the fluid with the moutul rbf600 and not remove all the old fluid?
